Specification of Letters Patent.

T 0 all whom it may concern:

Be it known that T, PERRY FLORA, citi- Zen of the United States, residing at Owingsville, in the county of Bath and State of Kentucky, have invented certain new and useful Improvements in Bit- Stocks, of which the following is a specification.

My invention relates to that form of wrench or brace in which a ratchet is used, operable in either direction, and having a handle carrying pawls engaging with the ratchet when the handle is operated in either direction, means being also provided for engaging both of the pawls with the ratchet so that the ratchet and handle will operate together in both directions.

The object of the invention to provide a very simple and convenient tool of this character having a handle projecting out at right angles to the body of the brace or wrench, whereby increased leverage may be secured, and also provided with a pressure knob which may or may not be used, as desired, this knob entering the shank of the implement immediately behind the tool held therein, but being detachable therefrom, if wished.

For a full understanding of the invention and the merits thereof, and to acquire a knowledge of the details of construction, reference is to be had to the following description and accompanying drawings, in which:

Figure 1 is a side elevation of one form of my improved wrench; Fig. 2 is a section thereof on the line 2-2 of Fig. 4; Fig. 3 is a side elevation, partly broken away, of another form of my wrench; Fig. 4 is a fragmentary section on the line 4 t of Fig. 2. Fig. 5 is a transverse section on the line 55 of Fig. 4.

Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.

My improved implement, in the form shown in Fig. 1, consists of a hollow body 2, shown in detail in Fig. 2, open at its rear end and extending laterally at 2*, this body constituting a sleeve which surrounds a shaft 5, as will be later described. The

rear open end of the body is closed by a covering plate 8 which extends along the angular extension 2 as shown, and held in place by screws 4 located at one end, and by screws 4; at the other. Carried within the body or sleeve 2 is the shaft 5 having at its rear end the ratchet 6 and at its forward end where it projects beyond the sleeve 2, the tool-engaging head 7 having therein the socket 8 for the reception of a tool, said head entering into an annular recess formed in the end of the body so as to give a very rigid bearing for the head and for the shaft. Mounted within the angular extension of the sleeve 2 are the opposed pawls 9. There are two of these pawls opposite to each other and engaging on opposite sides of the ratchet, said pawls being cut away so that while the bases of the pawls bear against each other, the tooth of each pawl is as wide as the ratchet 6, thus securing a firm engagement of the pawls with the ratchet. A screw 10 passes through the covering plate 3 and through the pawls to form a pivot pin for the same, the covering plate being countersunk to receive the head of the pin. Tn order that either pawl may move out of engagement with the ratchet teeth, each pawl has a laterally projecting lug 11 extending into the opposed slots 12 formed in the wall of the angular extension, the lugs being long enough to project through the wall when the pawls are in engagement with the ratchet. The end of the angular portion 2 of the body or sleeve and the end of the covering plate are re duced to receive a ring 12 which is freely rotatable around said reduced end and is held in place by a collar 13 or in any other suitable manner. This ring has a thickened wall 12 adapted to engage with either one of the lugs 11, and a spring 9 acts to force the lugs apart and pawls in engagement with the ratchet. The extremity of theangular extension 2 is screw-threaded to engage with a handle 14L- which is preferably hollow and provided with the cap 15. The hollow handle is adapted to inclose a variety of small tools which may be used in connection with the head 7. In order to hold the various tools in place within the head 7 I provide this head with a pivoted handle 14 may 30. p

' desired direction.

I have shown in Fig. 1 a screw driver A which may be either formed so as tobe received within the socket 8 of the headyor may ,be made solid with'the socket, as'desired.

In ,Fig. 3: Ishow a modified form of tool .in-which,.in addition to theparts abovedescribed, apressure shaft 20..is used. 1 Preferably'this is formedso asto be d'etachably engaged with the end ofthe-shaft 5, as by ;the screw threads 21,.the cap 3 being formed ;with an opening 13.for thispurpose. The

extremity of this shaft 6 .is provided-with a knob 22whichis swiveled-onfthe"shaft 6 I in any suitable manner.

' The operation of my invention will be obvious from the description. The a pro priate ,tool is inserted in the head 7 and held therein: by the latch, whereupon the p be turned vto rotate the ratchet shaft 5,=thus rotating the tool in the By. manipulating the ring 12,'it will be seen that one or the other of the pawls may be raised from engagement :with the ratchet, and thus. a movement of the-handle 14 in.one orthe other direction will act to rotate the. ratchet in one or; the other direction; It will also be obvious zthat by turning the ring so that both of the: lugs 10 are allowed to .move outward, both of the pawlswillbe in engage- .nient with the ratchet and therefore hold the ratchet from any .movement independ- .ent ofthe handle, and that thus the sleeve and-the shaft- 5 rotate together. Under ordinary-circumstances, it is only necessary .wtOOPGIELtG the tool with the-handle 14, but

wherev considerable pressure has to be apaplied to thetool, or where working with 'the tool extending upward,..then-*the pressureshaft with its knob is preferablyattached tothe end:of the: implement,as before described.

:-While I have-shown what=I believe to be; the preferable form ofv my invention, I

-.do not :wish: to .be: limited thereto, as itis obvious :thatmany changes might be made without departing from the spirit of the v invention.

"Having 1 :thus described the invention, what I claim is:.

.1.- In.an implementpf the character de- .scri.bed, a. shaftivhaving annenlarged sock- -aeted head at onezend-anda ratchet at the .eother, a. tubular-ibodyihaving a recess at its forward end to receive the inner end of the head and formed with a hollow angular extension circular in cross-section, the rear end of the body and rear face of the angular extension being open, a pawl pivotally mounted in the angular extension and engaging the ratchet, a cover-plate closing the rear end of the body and the rear face oftheangular extension having its outer surface rounded to conform to the rounded contour of the angular extension and the body, said plate, the body and the angular extension entirely housing the shaft, the ratchet and the pawl.

2. In an implement of the character described, a shaft having an enlarged socketed head at one end and a ratchetin the-other, a tubular body having a recess at its for- Ward end to receive the inner end of the head and formed with a hollow angular extension, the said angular extension in crosssection forming a section of a circle, the

rear end of the body and the rear face of the angular extension being open, opposed spring actuated pawls pivotally mounted in the face of the angular extension and having means for positively engaging one or :the other of the pawls"forshifting oneor itheother of the pawls out of engagement with the ratchet.

3. In an implement of the character described, a shaft having an enlarged socketed head at one end and a ratchet at the other,
